These DO NOT fit in the fusses in a 2021 Chevrolet HD Silverado 2500! The fuses in this truck have 3 prongs not 2. No idea why there are 3 prongs in my truck. Anyway these are a great idea and will be using these in other vehicles and boats. For that I give them 4 stars. They will fit in a 2006 Honda Ridgeline and any other vehicle with regular and mini fusses
